CLOSURE FOR CONTAINERS Filed May 20, 1936 Patented Sept. 6, 1938 UNITED STATES PATENT OFFICE CLOSURE FOR CONTAINERS Application May 20, 1936, Serial No. 80,839

1 Claim.

This invention relates to metal containers and more especially to containers having closures adapted to be tightly held so as to seal the container.

Heretofore considerable structure has been required to provide a quickly detachable closure or cover which, while in use, could be held tightly pressed to its seat on the container.

An object of the present invention is to provide holding clips for lapping and pressing against the closure when seated, these clips being mounted in a. new and novel manner so that it becomes unnecessary to employ separate specially attached fastening means for the clips.

Another object is to provide supports for the clips adapted to hold the clips so that they can be used in connection with a closure having a broad flange or apron depending therefrom.

Another object is to provide a structure which can be manufactured readily and at low cost.

With the foregoing and other objects in view which will appear as the description proceeds, the invention consists of certain novel details of construction and combinations of parts hereinafter more fully described and pointed out in the claim, it being understood that changes may be made in the construction and arrangement of parts without departing from the spirit of the invention as claimed.

In the accompanying drawing the preferred form of the invention has been shown.

In said drawing Figure 1 is an elevation of a portion of a metal container having a closure fastened thereon by means of the improvements constituting the present invention.

Figure 2 is a section on line 22, Figure 1.

Figure 3 is a section on line 3-3, Figure 1, the clip being shown by broken lines in released position.

Figure 4 is a section on line 4-4, Figure 3.

Referring to the figures by characters of reference, I designates a sheet metal container the top edge of which is rolled outwardly to form a tubular bead 2 the bottom portion of which is cut away at desired points as shown at 3. Fitted snugly in the bead is a stiff. bead wire 4 and at those points where the bead is cut away the wire is formed with depending angular yokes 5.

Mounted to swing on the bottom portion of each yoke is a clip 6 formed preferably of strong resilient metal, there being lugs I at one end of the clip which embrace the yoke so as to hold the clip thereto.

The closure 8 is adapted to fit down into the upper portion of the container and is formed with an annular flange 9 constituting an inverted channel the outer side wall of which forms an apron H) which can extend below bead 2. Packing II is seated in the channel so as to bear upon bead 2 when the closure is in position.

The clips 6 are so shaped and proportioned that after the closure has been placed in position, they can be pressed over the flange of the closure and will force it downwardly so as to compress the packing within the channel and upon the bead. Consequently the container will be sealed.

The free end portion of each clip forms a seat l2 which engages the top of the flange l0 when the closure is sealed and as this point of engagement is substantially in vertical alinement with the pivotal center of the clip, there will be no danger of the clip swinging laterally out of engagement with the flange l0 after the closure has been fastened. Each clip is of a strong resilient material and thus constitutes a spring which holds the clip constantly pressed tightly on flange Ill.

The lugs on the clips can be made angular as shown. Thus when a clip is swung outwardly and downwardly to the position shown by broken lines, the yoke will yield to allow the angle of the lug to move upwardly back of the yoke so that a flat face of the lug can come into position where it will be clamped between the yoke and the side of the container. Consequently the clip when thus located, is held against free swinging movement.

To remove the closure the free end of each clip. ii is sprung upwardly a suificient distance to allow the clip to swing outwardly from engagement with flange ID. The closure is then free to be unseated.

By providing depending yokes integral with the bead wire it is possible to dispense with special attaching means for the clips requiring riveting or welding and it is also possible to mount the clips where they will not be interfered with by the depending apron of the closure.

All of the parts are cheap to manufacture and easy to assemble.

What is claimed is:

A sheet metal container and a closure therefor comprising a body portion having an outwardly rolled hollow head at the upper end thereof, said head having cutaway portions, a wire disposed within said head and extending around the container, said wire being bent at said cutaway portions to form depending yokes extending downwardly along the outside of the body wall, and a resilient clip pivotally secured to each yoke and dimensioned so as to contact with said closure when turned to a position overlying the same for holding the closure on the container.
